Raila Odinga, leader of the Azimio la Umoja One Kenya Party, has rubbished the progress made by the Kenya Kwanza government led William Ruto, rating it at 30%,.
The families accused the police of using excessive power in handling protests, insisting that their sons were innocent and did not deserve to die by bullet.
MPs Nimrod Mbai and Clement Sloya said that former Nigerian president Olusegun Obasanjo has no moral authority to reconcile William Ruto with Raila Odinga.
Protests are regularly outlawed, with police setting up blockades to stop marching demonstrators and refusing to provide details of the rising number of dead, injured and arrested.
